TDK Statement On Fake 2X DVD-R Stamper Posted Friday, 6 December, 2002

" TDK Recording Media Europe has recently received reports of the production and sale of DVD-R discs that are not authorised or manufactured by TDK, but have TDK's manufacturer identification code. Confirmed products violating the TDK DVD manufacturer identification code include SuperX and Princo DVD media. TDK believes these discs will cause confusion and inconvenience to both consumers and recording drive manufacturers in terms of poor quality issues, and would like to take this opportunity to explain its position.

The manufacturer identification code is a piece of information engraved into the stamper, the core component of the optical disc manufacturing system. This unique code identifies the manufacturer of the disc and is read by the recording drive in order to adjust to the optimal recording settings dictated by the disc type. The manufacturer identification code is one of the underlying mechanisms for ensuring reliability. TDK co-operates with leading DVD drive manufacturers to ensure their DVD writers automatically detect the speed of the DVD media being used, in order to optimise performance. As a result, TDK DVD discs provide the highest compatibility and quality with all drives.

TDK discovered that DVD–R discs are circulating in the European market in violation of its manufacturer identification codes. TDK is not the manufacturer of these particular discs and takes no responsibility for them.

TDK has voiced objections in the strongest possible terms to the parties involved in both manufacture and distribution of discs linked with the unauthorised use of TDK’s manufacturer identification code. Considering that this type of conduct is detrimental to the entire industry, TDK has also explained the situation to industry groups including the RW Products Promotion Initiative (http://www.rwppi.com) and other involved parties.

TDK takes a firm position against the unauthorised use of manufacturer identification codes in order to prevent any inconvenience to our customers. The TDK name has become one of the world’s most respected brands in recording media and TDK will make every possible effort to maintain its trusted brand, relied upon by its customers.

您有要求一定要版面嗎？我買的G04是無mark的裸片，一次買50片的話他算我一片65塊，不知道這個價錢你覺得如何？
btw，首頁賣的那種有mark的G04，算算一片75塊。

我有買印 Pony 的 4x 片子, 光華商場裡面買的, 10 片 630 元...
75 元貴太多了吧.

問個笨問題，怎麼看G03，G04呢？因為最近要進入500A的魔爪了，要做一下功課。

大哥，這篇的標題難道你都沒看嗎？原發言人就已經在第一篇告訴你怎麼看啦...

大哥，我不說用片子的版面來辨認啦，我是說到店裡面去看的時候，有什麼條碼，或者是直接哪裡就會寫什麼編號是屬於G03或者是G04的片子。

他前面又沒有寫，奇怪。

另外一篇有寫...來看看吧...還有圖喔
直接辨識法...

我貼的圖，應該有說明那些是G04，那些是G03了吧。
除非老闆賣的片，都不是我買過的片。

這種我用過 是princo做的
燒錄的穩定度不錯
但是與日系的dvd player相容性不好
